forwardly to a int preferably outside the stove in which t e apparatus may be mounted. In operating the crank 19 is provided at one end with a socket portion 20. The socket portion 20 is provided with a hole in which is fitted the outer end of the bar 8. In said socket portion is provided a longitudinal groove 22, adapted to receive therein a peripheral projection 23, provided on the outer end of the bar 8. A lateral peripheral recess 24, connecting with the groove 22 and adapted to receive therein the projection 23, is provided in the socket portion 20. When it is desired to rock the bars 8 and 9 to and from the positions shown in solid and in dotted lines in Fig. 8, the operating-crank 19 is slipped upon the. outer end of the bar 8 to a position in which the projection 23 is either forward orto the rear of the recess 24. By then rocking the operating-crank 19 the two bars 8 and 9,.with their jaws 17 and 18, may be rocked or oscillated to and fro. The outer side of the crank opposite the socket portion 20 is provided with a handle 25, by which the bar 8, member 7, and grate-body 1 may be oscillated to and fro.

When it is desired to withdraw the member 7, so that cinders may be withdrawn through the opening 2, the crank 19 is moved to a position in which the projection 23 is in register with the recess 24, after which the crank 19 is turnedupon the bar 8, thus causing the projection 23 to enter the recess 24. The crank 19 is then drawn forward, thus drawing forward the bar 8, the bar 9, and member 7 to a position in which the jaws 17 and 18 are forward of the opening 2, at which time the cinders and ashes may be removed through the opening 2.

'Our invention may be modified in many -ways without departing from its spirit.

Having thus described our invention, What we claim, and desire to secure by Letters Patent, is

1. The combination with the body of the grate having an opening therethrough for the passage of clinkers, of a member slidably mounted on the body, and two rock-bars pivotally mounted on and movable with the slidable member and provided respectively with two jaws which overlap each other and which, when the slidable member is roperly positioned, obstruct the opening in the body.

2. The combination with the body of the grate having an openin therethrough for the passage of clinkers, o a member slidably mounted on the body, two rock-bars pivotall mounted on and movable with the slidab e member, and provided respectively with jaws which overlap each other and which, when the slidable member is properly positioned, obstruct the o ening in the body, and means by which rocking movement of one bar is transmitted to the other.

3. The combination with the body of the grate having an opening therethrough for the passage of clinkers, of a member slidably mounted on the body, and two rock-bars pivotally mounted on and movable with the slidable member and rovided with two aws which overlap each ot er and cooperate when the slide is properly positioned, to obstruct said opening in the grate-body, the jaws being formed so that when the bars are rocked in the roper direction, the jaws will elevate the fue l resting thereupon.

4. The combination with the body of the grate having an opening therethrou h for the passage of clinkers, of a member slidably mounted on the body, two rock-bars pivotally mounted on and movable with the slidable member and having two jaws one on each of said bars, said jaws overlapping each other, one serving to partially envelop the other jaw, and means by which rocking movement imparted to one bar'is transmitted to the other bar.

5. The combination with the body of the grate having an opening therethrough for the passage of clinkers and provided on its under side with uides disposed on opposite sides respective y of said 0 ening, of a member slidably mounted in sai guides, two rocking bars pivotally mounted on said slidable member and provided one with an arm having a slot and the other with an arm having a projection mounted in said slot by means of which rocking movement of one bar is transmitted to the other, said bars being provided with overlapping jaws which, when the slidable member is properly positioned, obstruct the opening in the grate-body, and a crank provided with means for engaging one of said rocking bars so as to impart thereto a sliding or a rocking movement when the crank-arm is correspondingly moved.

6. The combination with an oscillatable grate-body provided with an opening there through, of a member slidably mounted on said grate-body, two bars oscillatively mounted upon the slidable member and carrying two fuel-supporting devices comprising two partially-spherical jaws convex upon their upper sides and one serving as an envelop for a portion of the other, means by which one of said bars may be oscillated, and means for transmitting oscillation to the other bar therefrom.

7. In a grate, the combination with two rocking bars provided respectively with radial arms which engage each other and which transmit movement from one to the other, said bars having two artially-spherically-shaped jaws mounted eccentrically one upon each of said bars, one jaw partially enveloping the other, of a member upon which said bars are mounted.

8. In a grate, the combination with a slidable member, of a rocking bar mounted thereon and movable therewith and provided with a peripheral projection, and an operating- In, testimony whereof we affix our signacrank rovided with a socket fitted to said tures in presence of two witnesses. bar and having an inner longitudinal groove BURN AM B.
